Adds a curved segment, defined by two new points, to the path by drawing a Quadratic curve that intersects both the current coordinates and the specified coordinates (x2,y2) , using the specified point (x1,y1) as a quadratic parametric control point.

Usage

From source file:org.apache.pdfbox.pdfviewer.font.CFFGlyph2D.java

private GeneralPath transformGlyph(GeneralPath glyph) {
    // we have to invert all y-coordinates due to the moved 0,0-reference
    PathIterator iter = glyph.getPathIterator(null);
    float[] currentSegment = new float[6];
    Path2D.Float path = new Path2D.Float(iter.getWindingRule());
    boolean glyphTransformed = false;
    while (!iter.isDone()) {
        glyphTransformed = true;/*from w  ww . ja  v  a2  s .c o  m*/
        int type = iter.currentSegment(currentSegment);
        switch (type) {
        case PathIterator.SEG_MOVETO:
            path.moveTo(currentSegment[0], -currentSegment[1]);
            break;
        case PathIterator.SEG_LINETO:
            path.lineTo(currentSegment[0], -currentSegment[1]);
            break;
        case PathIterator.SEG_QUADTO:

            break;
        case PathIterator.SEG_CUBICTO:
            path.curveTo(currentSegment[0], -currentSegment[1], currentSegment[2], -currentSegment[3],
                    currentSegment[4], -currentSegment[5]);
            break;
        case PathIterator.SEG_CLOSE:
            path.closePath();
